Question

Find the length of the radius of the following circle. (x + 2)2 + y2 = 10 5 √(10) 100

Answer 1

For this case we have the following equation:

 (x + 2) 2 + y2 = 10

 We must remember that the standard equation of the circle is given by:

 (x - h) 2 + (y - k) 2 = r2

 Where r is the radius.

 Therefore, in the given equation the radius is:

 r ^ 2 = 10

 Clearing we have:

 R = root (10)

 Answer:

 The length of the radius of the circle is:

 √ (10)
